This article explores what factors determine the introduction of patents into a patent pool. We propose a dynamic analysis of 1337 U.S. patent inputs into 7 important pools. This analysis highlights a trade-off between firm and patent characteristics as the determinants of inclusion of patents...

This paper analyzes empirically the value - as measured by patent citations - of a set of 1363 essential patents belonging to 9 different patent pools. We find that pooled patents receive more cites than control patents having the same characteristics but not included in a pool. This difference...

After an introduction into the principle data and methodology, this study starts by providing a quantitative overview of the general features of standard essential patents (also called SEPs). It considers the occurrence of essential patents, how their existence has developed over time, and how...

The prospect of licensing patents that are essential to standards on an industry-wide scale is a major incentive for companies to invest in standardization activities. Most standard development organizations (SDOs) have defined intellectual property rights (IPR) policies whereby SDO members must...

This paper describes a new database of declared Standard-Essential Patents (SEPs), discusses methods for matching declared SEPs to specific standard documents, and presents empirical evidence on technology standards subject to declared SEPs. While there is a growing body of empirical research...

This article investigates the role of industry driven coordination mechanisms such as consortia and patent pools in the interplay between formal technological standards and patents. Building upon 64.619 declarations of essential patents to major international Standard Development Organizations...
